Amek Angela Frequency Response

Today I've checked the frequency response of my Amek Blue Angela at few different outputs using Waves Q Clone and this is what I've found:

Can someone please re do this test on his Angela and see if it acts the same?
Master buss:

Buss 1:

Aux 1:

Insert Send:

I've made this test on few different A10 modules and checked few different Buss Outputs and it acts the same.
I've also never recapd the console so this loss might cause due to old caps?

Pretty much impossible to see the scale markings on your small pictures. All audio gear will show a similar response. Its the magnitude of the dip, and the frequency it occurs that is important. And bear in mind, you dont really hear 20 Hz or 20 kHz, so why would you want to record it?

Yes, it's hard to see what's going on on those little pictures, here's a larger images
Buss 1 - 20Hz at -12db

AUX Send - 20Hz at -6db
https://ibb.co/WH4XMZW
Insert Send - 20Hz at -2db
https://ibb.co/khqV5MW
Master Out - 20Hz at -7db

And you're probably right, most of the time I'n cutting anything below 50 Hz and above 16kH...

-12 db at 20 hz will introduce a lot of phase shift besides the lack of low end depth. Besides the failing caps some are also mounted backwards. Some don't need to be there, not any DC offset. 90% of them can be bypassed with a wire if low offset opamps are used.

Yeah it would most likely be much worse into a 600ohm load. Jim’s absolutely correct. A recap at the very least to get back to normal spects and using low offset amps with bypass wires on some caps would improve phase response at the low end. Also could experiment with higher caps in the feedback portion of the amps to improve high frequency response and transient distortion . Good luck...
